WD Tappets

Andy Airgood · Oct 17, 2019

Does anyone know where I could get replacement bushings for the tappets on my WD? Also, is it possible to replace the pads on the valve end of the tappets? It looks like it should be but have no idea if replacements exist.

I didn't know there were bushings in the block. Parts book doesn't show them. I'd guess you'd need a shop to turn new ones. You can have the tappets flattened as well. Not sure you can replace anything on them.

I'm gonna guess the O.P. is talking about rocker arms???

Here is a link to the AGCO Parts catalog for the WD / WD45 / WD45D TRACTOR; POWER UNIT. Be sure you get the right pages for your machine as this catalog covers several. You can see the replaceable parts and it appears the parts (If you were referring to rocker arms, not tappets) you asked about were not offered as replacements. It will also give you the part names commonly used and you can do web searches using the part numbers to see if offered by an aftermarket source. (Tappets run on the cam shaft lobes and move the push rods.)

Thanks everyone. Looking at the parts book I am talking about the bushing in the rocker arm. Didn?t see a WD in the parts blood but a D17 looks like the bushing is not serviced. Is that the same for a WD?. Looks like if the bushing is worn it takes a whole new rocker arm.

I see the link I posted directly to the WD parts book has a problem so:

Go to AGCO parts books, click on view books in the guest user section (unless you are set up with a log in through your dealer). Enter WD in the search box on the next screen and search. When I do that the parts book (# 79001544) for the WD / WD45 / WD45D TRACTOR; POWER UNIT - W226 is the first one listed.

And yes the bushing is not serviced. For prior to 289000 it is not mentioned and for 289000 and up it says not serviced separately. It shows as some of the early WD45 diesels had more serviceable parts including bushings.
